MBARI
The first stage of the network will consist of 62
km (39.5 miles) of submarine cable and a single
science node located 1,200 meters (almost 4,000
feet) below the ocean surface. The node will have
four separate ports (docking stations) for
oceanographic instruments. Each port will support
bi-directional data transfers of up to 100 Mbits
per secondcomparable with some of the fastest
land-based commercial data networks. The cable
will also supply up to 10 kilowatts of power to
the instruments-enough power to supply a small
neighborhood, and several orders of magnitude
more power than could be supplied using batteries
alone
